3 Claims.

This invention relates to articles of furniture, but more particularlyto supporting frames for gliders or the like and an object is to producea simple, inexpensive, sturdy and reliable frame of this character whichcan be readily and conveniently set up for use without the use ofspecial tools, screws or the like, and can be packaged for shipment tooccupy a minimum of space.

Another object is to produce a frame for a glider or the like having thenew and improved features of construction and arrangement hereinaftermore fully described, and for purposes of illustration, an embodiment ofthe invention is shown on the accompanying drawing in which:

Figure 1 is a perspective view of the frame in position of use;

Figure 2 is an enlarged fragmentary top plan view of the connectionbetween one end of the connecting rail and the adjacent upright supportor standard;

Figure 3 is a sectional elevation substantially on the line 3-3 ofFigure 2; and

Figure 4 is a fragmentary view showing the manner in which the rail isconnected to the upright standard.

The illustrated embodiment of the invention comprises a frame for aglider or the like, having frames or standards Ill and I I which aredisposed in upright position. The end frames l and II are connected attheir lower end portions by a connecting rail or rod I 2, the oppositeends of which are detachably connected respectively to the end frames.The end frames or standards In and II are similarly constructed anddescription of one will suffice. Furthermore, inasmuch as the connectionbetween opposite ends of the connecting rail l2 and the end frames isthe same, only one connection will be described in detail.

Each of the end frames I0 and II consists of a single length of rod ortubing which is bent to provide upwardly curved sides l3 and I4 whichare integrally joined at the top. At the bottom the sides l3 and I 4 areintegrally connected to inwardly extending base portions l5 and I6respectively. These portions are shown resting on rubber blocks I! whichare suitably grooved to fit the contour of the rod or tube. The lowerportions of the sides [3 and I4 are in this instance connected by crossrods l8 which are arranged in parallel relationship and are suitablysecured at their opposite ends in the side portions of the frame. Theserods not only enhance the appearance of the end frame but also impartsturdiness and rigidity to the structure.

Integrally connected to the respective base portions l5 and I6 andextending inwardly toward the opposite end frame are end portions l9 andrespectively. As shown in Figure 2 the end portions are disposed atsubstantially right angles to the adjacent base portions, are spacedfrom each other and disposed substantially in parallel relation withrespect to each other. As will hereinafter appear, the space between theend portions l9 and 20 provides a socket to receive the adjacent end ofthe connection rail or rod l2, the end portions I9 and 20 also servingto provide a foot for the respective end frame or standard. Bridging thespace between the end portions l9 and 2!], providing a connectiontherebetween and also forming an attaching means for the rail I2, is a15 pair of rivets or pins 22 and 23 which are spaced from each othersubstantially as shown in Figure 2.

The main portion of the rail I2 is spaced upwardly from the supportingsurface by opposite end portions 24 as indicated in Figures 1 and 3which are disposed in a plane below the main portion but in parallelrelation to it. Formed in the extreme ends of the rail l 2 is a notch 25which is adapted to fit over the pin or rivet 22. Spaced inwardly fromthe notch 25 and disposed on the upper side of the rear end portion 24,is a notch 26 which is adapted to fit over the pin 23. In connecting therail to the end frame, the notch 25 is first engaged over the pin 22with the respective end frame disposed at an angle to the rail, asindicated in Figure 4, and thereafter the pin 23 may be brought intoengagement with the notch 26. It will be understood that each of thesupporting standards or end frames l0 and II are similarly connected tothe rail l 2.

In order to hold the parts in assembled relationship and to preventaccidental slippage of the rail from the end frames, a latch piece 21 ispivotally mounted centrally thereof on the rear end portion 24 betweenthe notches 25 and 26 by a rivet 28. After the parts have been assembledin the desired manner the latch piece 21 is turned so that the endportions are disposed over the end portions l9 and 2|] of the respectiveend frame. In this manner the rail is held securely in position. It willbe apparent that the parts can be readily assembled or disassembledwithout the use of any special tools, screws or the like, enabling theframe to be readily and conveniently set up without particularinstructions or teaching.

It is to be understood that numerous changes may be effected in thedetails of construction, arrangement and choice of materials withoutdeextreme end thereof and a notch in the upper side thereof spacedinwardly from the first notch, said notches receiving said pinsrespectively, and a latch member holding each end of the rail andadjacent frame in assembled relatiom 2. In a glider, a pair of spacedupright end frames, each frame having an inwardly extending footconsisting of laterally spaced rod-like parts, a pair of pins spacedfrom each other connecting said rod-like parts, a rail connecting saidend frames, each end of said rail having a notch in the extreme endthereof and a notch in the upper side thereof spaced inwardly from thefirst notch, said notches fitting over said pins respectively, and alatch pivoted on the upper side of the rail and adapted to be swung to aposition over the respective rod-like parts for holding the parts inassembled relation.

3. A glider comprising avpair of spaced upright end frames, each endframe comprising a length of rod bent to provide the frame portion withthe ends thereof extending inwardly in substantially parallel spacedrelationship thereby to form a foot, a rail connecting the end frames,interengaging parts on the respective feet and ends of said railconnecting the frames and railtogether,

and releasable means for holding said interengaging parts fromseparating.
